What's phase switch please,

Depending on the placement of your sub, and the room it is in, it is possible for it to end up being out of phase with your speakers. Simply place the sub in its location, sit in the general seating area, and have someone switch the polarity switch back and forth. Which ever position gives you more perceived bass, is the position you want to stick with. This is the position that puts the sub in phase with your speakers. Sometimes, in order to hear the difference, you may need to crank up the sub. This will increase the bass enough to hear whether or not the sub and speakers are canceling themselves out. Jeff
